LOUIS B. WACKMAN, OF ST, LOUIS, MISSOURI.

BARREL-SEALIN G DEVICE.

Application filed March 12, 1921. Serial No. 451,855.

To all whom it may concern: I

Be it known that I, LoUIs B. WACKMAN, a citizen of the United States of America,

v and a resident of the city of St. Louis and State of Missouri, have invented certain new and useful Improvements in a Barrel-Sealing Device, of which the following is a specification.

The primary object of this invention is to provide an improved device for sealing the mrlatallic lids or cover plates of metallic barre s.

Another object of the invention is to provide improved adjusting means for the sealing rollers of this improved device.

A further object of the invention is to provide the adjusting means of the expanding or sea-ling rollers with an improved adjustable limiting mechanism so that the rollers cannot be moved too far outwardly in the expanding or sealing operation.

Other and further objects will appear in the specification and be specifically pointed out in the appended claims, reference being had to the accompanying drawings exemplifying the invention, and in which,

Fig. l is a plan view of this improved device.

Fig. 2 is a longitudinal section taken on the line IIII of Fig. 1.

Fig. 3 is a transverse section taken on the line IHHI of Fig. 1.

With reference to the accompanyin drawings, this improved device is comprise :2: of an approximately triangular shaped frame 1, and secured to the rear cross member 2 of said frame is a pair of expanding rollers 3, said rollers being spaced apart and arranged horizontally on the underside of the frame by vertically arranged screws or pins 4.

Arranged centrally of the cross member 2 is the boss 5, said boss being threaded interiorly as designated at 6. and in engagement with the threads 6 is the threaded portion 7 of the horizontally extending bar 8, said bar having a turning handle 9 secured at one end, the opposite end of said bar being turnably engaged within a sliding block 10 and secured to said block by the pin 11 which is carried by said block and engaged within the grove 12 of said bar 8. The block 10 is slidably mounted within a dovetail guideway 13 which is formed in the frame 1 in opposite disposition from the boss 5, said block 10 having a horizontally arranged expanding roller 14 secured thereto on' its underside by a holding screw 15 Forming part of the frame 1 and arrangedin alinement with the guideway 13 is a boss 16, said boss beingthreaded interiorly as designated at 17 and in engagement therewith is the threaded end 18 of the horizontally extending bar 19, said threaded end 18 bearing an adjustment nut 20 which is adapted to jam against the end of the boss 16.

As already related this improved device is for the purpose of expanding the closure plates or lids of metallic barrels after they have been mounted in closing position to the barrel and in the operation thereof the device is mounted as shown in Figs. 1 and 2, onto the closure plate A, in which the expanding portion 21 of the rollers 3 and 14 will be engaged against the side wall B of the plate A, while the rollers themselves will rest on the depressed portion C of the plate A. If, however, the portions 21 of the rollers do not engage the handle 9 of the bar 8 is turned in a right hand direction in which the block 10 bearing the roller 14 will be forced outwardly until the expanding portion 21 thereof will engage the wall B of the plate A and continued turning of the bar 8 will also force the expanding portions 21 of the rollers 3 against the wall B thereby placing the device ready for operation.

The bar 8 is then engaged by the operator at a position adjacent the handle 9 and at the same time the extending end of the bar 19 is engaged, one of said bars being pulled toward the operator while the other bar is pushed away from the operator thereby presenting a horizontal turning movement to the frame 1 in which the rollers 3 and it will be forced to revolve against the wall B of the plate A, and during the turning of the framethe handle 9 of the "bar 8 is engaged and turned in a right hand direction thereby forcing the block 10, bearing the roller 14, outwardly and incidentally the pair of rollers 3 so that an under expanding groove D will be eventually formed in the wall B side wall B, the

of the plate A beneath the depending porthereb 1 creating a split or break in the side wall, t e threaded end 18 or the bar 19 is adjusted to a position Within the gu'ide'way 13 of the sliding block 10 so that the outward 5 travel of said block Willbe limited on account of said block engaging the protruding threaded end of the bar 19, the adjusted position of the bar 19 being held by the nut 20.

After the sealing operation, it is obvious that the roller ll is drawn inwardly by the manipulation of the bar 8 so that the frame holding theroliers can be removedrrom the plate A. i i v What I- claim and desire to secure by U. S. Letters Patent is:

1. In a barrel sealing device, a frame having', a series of expanding rollers, a. sliding block carried by said frame supporting one of said rollers, meansv for adjusting said block, and other adjustable means for limiting the travel of said block.

2. In a barrel sealing device, a frame having a series of spaced apart rollers, a sliding block carried by said "frame for supporting one of said rollers, an adjusting bar secured at one end to said block, and adjustable means earried by said frame for limiting the travel of said block.

3. In a barrel sealing device, a frame having a pair or spaced apart rollers, a sliding block carried by said frame bearingan expanding roller, an adjusting bar secured at one end to said block for adjusting it away from or towards said pair of rollers, and a second bar tnrnably mounted in said frame adapted to limit the travel 0i said block.
